java - JavaFX draw to image -

How can I get attracted to an image similar to canvas in JavaFX? Provides advanced drawing functions such as GraphicsContext2D , not by pixels. I'm trying to create multi layered canvas , and using another canvas component for each new layer looks like an overlap or it's correct and only preffered method is? Using multiple instances (one for each layer) is a recommended way to create a multi-layered canvas.

This method of making a layered canvas system (using A) is documented and displayed.

Your other option is not to use the canvas, but instead, use (), by placing the layered pan (one layer per layer) inside the visual graph node and all the layer pan inside one . You can convert the resultant stackpan to an image at any time by turning on the node API on stackspan.

Are not even the APIs that maintain the canvas? Since all the tasks were only put on grossable data buffers and sung on the event?

Yes, pulling the canvas API immediately is a little bit of a misnomer as you say it does, however, I think about APIs as APIs perceptually It helps to think about the API because it shows a lot to the developer using APIs, this is an implementation description, which is a subdivision of the data structure created to help in initial rendering The industry.

As far as I understand the implementation design, when you issue the order drawn on a canvas, it is usually placed in a buffer and the buffer is thrown into the image texture when the canvas The first is rendered for. Therefore, orders are made only in internal implementation, as long as not before the render event. If you draw further canvas on the forward pulse, those extra commands will be buffer, then the next pulse will be flown in the rendering phase.

For example, if you issue 1 million drawing commands for canvas in a pulse you will see a break because those commands are buffer and then sung, but you can The screen will not show up gradually 1 million times, only one update If you issue 10 million drawings in 10 pulses of 1 million orders, you will see screen updates 10 times. You have to issue a large number of drawing orders in the canvas to see such behavior.

If you are doing, then it is important to understand the implementation of the results properly, but otherwise there is nothing that you need to worry about. I do not have a great chance that this The details of the implementation will have serious performance effects for your project.
